How to show ShowDialog () from MDIChild form correctly?

I have an MDIChild form that should show a dialog. I am currently doing this so from within the mdichild form ...

f.ShowDialog(Me)

Should i use f.ShowDialog(mdiparent)?

What is the difference when setting up an owner before a call ShowDialog()?

The difference is in which parent the dialogue belongs. If you explicitly specify the parent, then this window has a dialog. If you do not install it (using the parameterless version of ShowDialog), then the current active window of your application will have a dialog box. This is on MSDN , by the way.
